' WELL-DRILLING APPARATUS.

Specification of Letters Patenti Patented Nov. 19, 1907.

i To all-whom it may concern:

Be it known that we, WILLIAM H. ULLMAN and MILES OKEY, citizens of the United States, residing, respectively, at Stafford,in

.thecountyof Monroe and State of Ohio, and

Zanesville, in the county of Muskingum and Stateof Ohio, have invented certain new and useful Improvements in Well-DrillingApparatus, of'lwhich the following is a specification.

. vOur invention relates to apparatus for drilling wells and particularly to a form of i'asasource of motor such apparatus especially designed for use where gas or gasolene engines are employed power.

1 One" object of our invention is to provide such a form of apparatus as -will admit of run- I -ning vthe bull-wheels either way in raising or speed.

lowering the tools without the aid of cog wheels while the engine moves ahead at full A further object is to provide means whereby the" ropelling power may be connected to move t e supporting truck either backward orfforsward at option while the-engine moves aheadcontinuously. g g I Thef'advantages of the above features will beyreadily apparent in connection with ages engine as a source of power since it is well i when running known that such engines are most efficient h continuously in one direction, andean with difficulty be reversed.

QA still'further object of our invention is to so dispose the bull wheels in legs on the front {end of the portable machine that a direct vertical pull will be obtained and liability of the rear end of the truck to lift will -be avoided.

" sctipe outlined in the appended claims.

eferring to the accompanying drawings wherein the same parts are designated by like reference characters, Figure 1 is aside elevation, a convenient means for l fting the derrick being lllustrated 1n dotted lines; Fig.

2 is .a plan view, the derrick being omitted to better illustrate the parts underneath; Fig. 3 is a vertical section through the apparatus; Fig.4 is a detail view illustrating the manner of mounting the sand reel and Fig. 5 is a detail view illustrating the frame for mounting one of the belt tighteners.

1 is the frame of a truck having'rear wheels 2, 2 fixed to an axle 3, journaled in said frame and front wheels 4, 4 on an axle 5, the latter bein ivoted at 6, centrally at the front end oft e truck. A driving shaft 7 is suitably journaled in bearings at the rear of the machine. Said shaft carries fly wheels 8, 8 to be driven by any suitable gas or oil engine (not shown). The engine may be mounted upon the rear end of the truck which is provided with stout cross beams 10 to constitute an engine base. The shaft 7 is provided with a belt pulley 11, adapted to receive a main driving belt 12. Said belt drives a large mainbelt wheel 13 fixed upon a shaft 14 and from this shaft is taken power; first to raise the drill for its reciprocations in drilling by means ofthe crank wheel 15 with antifriction disk 16 on the crank pin thereof the arrangement being. such that the lift of the drill is four times the arm of the crank -wheel; second todrive the bull wheels by means of belt pulley 17 thereon, and third to,

propel the truck either forward or backward at 0 tion by means of the gear pinions 18 fixed thereon.

The bull wheel shaft 19 is securely mounted in stout le s 19 which extend upward and somewhat orward from the front end of the truck and said le s are braced by suitable stays 19". One 0 the bull wheels is formed to receive the driving belt -21 and hence receive power from belt wheel and shaft 14 as shown. 22 is a tightening roll which is adapted to be pressed upon belt 21 from above atl option to make the same effective for driving, by means of a lever 23 suitably pivoted to a brace 19" as shown. A link 24 connects the other end of lever 23 to an operatin handle 26 pivoted at to a leg 19. It wil be understood that the belt 21 is loose enough on belt wheels 17 and 20 so as to normally slip thereon and only transmits a driving impulse to the bull wheels when the above described tighteriin device is operated. It is apparent that t 's constitutes a very convenient and easily operated means of connecting the bull wheels with the source of power and disconnectin the same therefrom. The other bull whee 28 is partially encompassed by a brake strap 27 and said strap is arranged to be operated I 'rear axle and'thus 1O in lever 38, a friction whee139 is ada ted to power is'furnishedto draw up the'said line :(notshown) and coil the same up nward position so that friction'wheel 39 is disengagedlb'y means of a spring 42 fixed at its opposite ends to said lever and to the this backward position a frame. -"When in I brake wheel 40 on the drum shaft36 is in engagement with a brake member 41=-and the saidreel is then pretvented from move- 'ment.

' j rear axle 3' fordriving the truck forward or backward'by means ofa shaft-43. Said shaft is journaled "at one end in afixed bear- .in'g'44 in the'frame and at the other end 1n a laterally movable bearing 45 carried on a ,pivoted bar 46. The bar 46 is pivoted-at47 to the frame and is adapted to be swung) on ivot by engagement with a screw 'olt fiichf-is suitabymounted for rotation by a steering wheel-48' but held'from' longitudinal movement-in thei'fiarn'e, Such lateral movement of thefrontend of shaft 43 'causesagear pinion on its end to be engaged with either one ofthe twojpinions 18 on shaft 14"acoording tothe direct on of movement desired, "A; pinion 49 on the rear end of shaft 43 meshes with a'gear'50 fixed on the h ri ing' mpu transmitted to the truck. When the apparatus is in position" for drilling the front end .of'shaft 43 is moved to an intermediate position so that neither of the 'nions 18 is in v 1 driving engagement' therewit li The pivotal movement ofthe front axle may be controlled by a worm shaft 51, hav.

ing' thereon a worm 52 adapted torotate a "drum 53 by aneans of. a suitable wormwheel thereon.v Said drum 53 in its rotation shifts the front axle as desired by means of bands 54 as will be readily understood.

Brace rods "55 may extend from the'sides l of the-frame to the klng' bolt 6 to strengthen the structure. e

V. 'A' foot brake 56'for the main drive'w-heel 13 is provided, the same being'journaled at 57 and providedwith an operating foot piece 58 disposed for convenient manipulation.

The main driving belt 12 is loosely mounted upon its-belt wheels and a convenient s5 tightening means therefor is provided' in the is thrown forward and thus on drum- "36; The lever38 is normally held in a back- Power is communicated from shaft 14 toform of'a roller 59 adapted to be pressed u on the topof the same. Said roller is carrier by a frame 60 adapted to move vertically in suitable guides 61. A horizontal bar 62 may be fitted to the top'of said guides to serve as a rest for the-derrick when the same is lowcred for transportation. The frame 60 is moved downward when it is desired to make the belt 12 operative by means of a lever 63 pivoted to a suitable standard and arranged a convenient leverhandle to be operated by 64 likewise pivotally mounted. In Fig. 1 the cable a is shown coiled around the bull wheel shaft, the operative end thereof passing around the crank pin roller 16 thence up over-the crown pulley 33; andhaving the In dotted lines in said figure is shown acon- *larly well designed. The drilling stem't has venient method 'ofraising the derrick forwhich our improved apparatus is particu-' drilling stem b on the end thereof. 7

its one end'inserted between the cross bars i '35- and a hitch ofthe cable is'taken around the projecting end thereof. The engine 'is a parent that the easi y lifted.

. The manner of operation of our machine will it is thought be easily understood from derrick is quickly and the foregoing descri tion, and its many advantages will-be rear. ily apparent. The bull wheels and operating parts being in the front power being now applied to the bull wheels it end of the truck a direct vertical pull is ob tained 'wherefrom'lateral strains are avoided and greater efficiency attained. The lifting of the drill to four times the crank wheel is accomplishedby the arrangement' as shown, in having the movable section of cable a which supports the drill?) from pulley 33 pass loosely around the antif-riction disk 16 and the' fixed end ofthe cable a attached to the bull wheels 28, at a 1 00 arm of the r point above the highest point reached by the I crank pin on wheel 15. By this arrangement the length of cable between the upper pulley 33 and disk 16 is increased or. decreased four' times the arm, as the crank wheel 15 is rotated.

' In transporting the machine, should'it get stalled in the object and'by assing' the line around-the bull wheel shaf tracted by' the engine power very easily;
